Ok.
Once I extend SimplifyIndVar, e.g. the simplifyUsersOfIV function. How I
can add a regression test for the extension? simplifyUsersOfIV is not a
pass.

Hi Eli,
Thanks. Do you mean ideally we should extend SimplifyIndVar to do the
sdiv->udiv replacement?
Thanks

retpoline mitigation and 6.0
I've landed the patch in r324449.
Before we merge this into two different Clang release branches and almost
immediately release one of them, I would really like someone to confirm
that this patch works well with the Linux kernel. David, if you're up for
that, it would be great. Alternatively, Guenter or someone else here can
help.
